2 ohm speakers available?

Hey are there any good 2 ohm front a rear speakers on the market. I see a mostly 4 ohm speakers although amps adverstise their amps at the 4 and 2 ohms ratings. Why would they do that if there arent any 2 ohm speakers

each speaker will have its own channel so none will be run in parralell. I am just trying to get the most out of my amp. It boasts 100w rms per channel @ 2 ohms and 65w rms per channel @ 4 ohms so it leads me to believe that I should get 2 ohm speakers right?

There are differences between speakers with different impedences, as to how they play and how they sound. I have to go move a desk, so I don't have time to explain it all (and probably, I'm not qualified to do it justice either). This might be a good starting point for some research: http://www.hometoys.com/htinews/feb0.../impedence.htm

I went into a car audio store the other day and i told the salesman (looked like the owner) my setup and how i wanted 2 ohm speakers and he tried to steer me away from them. I kinda go the feeling that he was doing that becasue he didn't have any 2ohm speakers.

I am still not sold on the 2 ohms but would like to hear them in person. I would love all of the extra power
